Calculate Total Price And Display Total In Order Class

Oct 11, 2014

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.

My main class

package useorder;
import javax.swing.*;
public class UseOrder {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Order.display();

[Code] .....

The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?

How To Calculate Total Age In Months And Store As Variable

Feb 9, 2015

I was wondering how can I calculate total age in months and store it as variable? this is what I have so far:

*
* You will ask the user to provide their name (as a single word, assume first name here)
* You will ask the user their age in full years (no fraction or months)
* You will ask the user how many full months since their last birthday (again, whole numbers here).
*
* You will use this information to calculate the user's age in months and use that information to print out a greeting.

Create A Program That Calculate Price Of Carpeting For Rectangle Rooms

Apr 23, 2014

I am not getting any syntax errors but the program simply does nothing when I run it.

I literally just get "run: BUILD SUCCESSFUL (total time: 3 seconds)".

So basically, I need to create a program that calculates the price of carpeting for rectangle rooms.(multiply the area of the floor by the price per square foot of the carpet).

-The RoomDimension class should have two fields: one for length and one for width, and a method that returns the area of the room
-The RoomCarpet class that has a RoomDimension object as a field, a field for the cost of carpet per square foot, and a method that returns the total cost of the carpet

Here is what I have:

package roomdimension.java;
public class RoomDimension {

private double length=0;
private double width=0;
private final double area = length * width;

public void RoomDimension(double len, double w)

[Code] ....

Client Class - Cannot Get Total Price To Recognize Surcharge

Apr 26, 2015

I am almost finished with my code. The only hangup I am having is that in my client class, I can't get the total price to recognize a surcharge.

This is my output:
-------------------------------------------------
Your order consists of:

coffee, type mocha, size large, cost: $5.8
tea, flavor earl grey, size medium, cost: $3.6

The total cost of your order is: $8.4
----------------------------------------------------
Notice that the total should be $9.4, rather than $8.4. It is odd because I was able to add a surcharge to my coffee(50 cents), and it does in fact recognize it when calculating the price of the coffee. So why won't my totalPrice in the client class recognize it?

Here is my Client class:

public class CoffeeShop {
public static void main(String[] args)
//One coffee
Coffee coffee = new Coffee(16,"mocha");
coffee.set_price_per_oz(coffee.size);

[Code] ....

Cumulative Sum - Display Total Price From All Loops Added Together

Feb 27, 2014

In the code below, under calculations, I have x=totalPrice+xXxXxX. Obviously the x's were just place holders, but I wanted to know if there was any way to add something there so the program would tally the totalPrice, store it in the x variable outside the loop, so when the loop ended it would display the total price from all the loops added together where I have System.out.println("TOTAL OF ALL ORDERS: $"+ round.format(x)); at the very end.

Java Code:

import java.util.Scanner;
import java.text.DecimalFormat;
public class ModifyOrderV2TEST
{
public static void main(String [] args)
{
//Rounding
DecimalFormat round = new DecimalFormat("0.00");

Pass Objects From 3 Different Methods At Random To Different Class And Store In Array?

Jun 8, 2014

in my progrm there are three diff array of objects...namely garments..gadgets and home app...now one who buys from each of these sections will have to make a bill at last...when he choses to make the bill he will be shown the list of products he bought and their details (like price...brand...etc)...so i thought that while he orders each product(which is done in a previous method called purchase()...)....(each product is stored as an object in there diif arrays namely garments...gadgets ...appliances)....each of those object will be copied in a new array in a diif class...then that array print will give me the desired result...

is this approach correct...?and if its correct then how can i pull out a specific obj frm a stored array of object and then save it in a new array....?

Java Program That Specifies Three One-dimensional Arrays Names Price / Amount And Total

Dec 2, 2014

Recently I have missed a few weeks of my class due to family emergencies. Because of this I have missed very important lectures. My professor has assigned me the following assignment:

Prices Write a Java program that specifies three one-dimensional arrays names price, amount, and total. Each array should be capable of holding 10 elements. Using a loop, input values for the price and amount arrays. The entries in the total array should be the product of the corresponding values in the price and amount arrays. After all the data have been entered, display the following output:

Total Price Amount

==== ==== ======

Under each column heading display the appropriate value.

I know how to display everything using printf, how to create the actual arrays and define the array size, but I am confused on how and what loop to use and how to construct it. This is what I have managed to write up so far:

import java.util.Scanner; // Imports the Scanner class
import java.text.DecimalFormat; // Imports the DecimalFormat class

public class Prices
{
public static void main(String [] args)
{
double[] price = new double[10];
double[] amount = new double[10];
double[] total = new double[10];

// Create a new Scanner object
Scanner keyboard = new Scanner(System.in);
} //End of main method
} // End of public class

Electricity Bill Project - How To Incorporate Rate Per Month And Three Rate Zones

Jan 30, 2014

I am not sure how to incorporate the rate per month and the three rate zones.

Problem: Electricity billing charges vary with the season and amount used.

Southwest Power and Light provides electricity at the basic rate of $ 0.10 per kilowatt for the months December through February, 0.12 per kilowatt for the months of March through May, and 0.15 per kilowatt for the remaining months.

Customer billing is divided into three rate zones: 0-350 kilowatts, 351 – 500 kilowatts, and above 500 kilowatts. Usage up to 350 kilowatts is billed at the basic rate. Usage between 350 and 500 kilowatts is billed at 10% above the basic rate. Above 500, billing is 25% above the basic rate. These surcharges apply only to the usage falling within the respective rate zone.

Create Country Object And Store In Array

Oct 12, 2014

Write a program that prompts the user for information about some countries, creates an object for each country, and then stores the objects in an array. After the user has entered information about all the countries, your program should print out which countries in the list have the smallest and largest area and population density. Assume the user will enter information about at least one country but that the program will not have to store more than ten countries in the array. The user will indicate that they are done entering countries by typing "DONE" for a country name. Here is an example of what your program must look like when it is executed (user input is shown bold)

Please enter the name of a country: United States
Enter the area in square km and population of United States: 9827000 310000000
Please enter the name of a country: Mexico
Enter the area in square km and population of Mexico: 1973000 122300000
Please enter the name of a country: Canada
Enter the area in square km and population of Canada: 9985000 35160000
Please enter the name of a country: Liberia
Enter the area in square km and population of Liberia: 111370 4294000
Please enter the name of a country: DONE

Liberia has the smallest area at 111370 square km.
Canada has the largest area at 9985000 square km.
Canada has the smallest population density at 3.521282 people per square km.
Mexico has the largest population density at 61.986822 people per square km.

I don't know, I'm really confused with this Java program. I don't know how to do the main part of the program where the user inputs, array, and the output.

// Access the Scanner and ArrayList class by importing the java.util package.
import java.util.Scanner;

/** Project - A Country Object
* The purpose of this program is for the user to enter some information at most 10 countries. After the user has entered information about all the countries, the program should print out which countries in the list have the smallest and largest area and population density.
*/

public class Country
{
private String countryName;
private int theArea;
private int thePopulation;
public Country(String countryName, int thePopulation, int theArea)

Calculate And Display Price Of Each Object Each Year For 5 Years

Apr 18, 2015

For this program I am calculating the annual costs of 5 office supplies (user input) each with a 5.7% inflation. The user inputs the cost of each object and my program must calculate and display the price of each object each year for 5 years. I already have this part. What I need is how to add the total costs of all 5 supplies per year and display each total cost. Here is the program:

import java.util.Scanner;//Using keyboard to enter data
//Start of Class
public class OfficeSupplyCalculator {
//Start of Method
public static void main(String args[]) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the first item");

[Code] .....

At the moment all I get for the grand total loop is the same number showing up 5 times. I feel like the problem is how I am declaring the grandtotalperyear variable but I'm not sure what is wrong.

Saving Student Grades In Int Array - Pass Rate 50

Apr 8, 2014

prompts user for the grades of each of the students and saves them an int array called grades. Your program shall check that the grade is between 0 and 100. program should then check if the grade is equal to or greater than 50, where 50 is the pass rate.

A sample output :

Enter the number of students: 3
Enter the grade for student 1: 55
Enter the grade for student 2: 108

Invalid grade, try again...

Enter the grade for student 2: 56
Enter the grade for student 3: 57

The average is 56.0
The maximum is 57
The minimum grade is 55
The number of fails is 0
The number of passes is 3
..

I am quiet stuck on this one.

For Loop - Calculate Total Of Series Of Numbers?

Nov 10, 2014

So basically, I've been trying to create a for loop that asks the user for a number between 1 and 30, then calculates the total of the series of numbers. For example, if 15 is entered, the calculation should be 1/15+2/14+3/13+...15/1 which would equal approximately 38.1. The problem I'm having is that the code doesn't loop whenever I type a number for some reason, which results in a very incorrect calculation. Here is my code so far:

import java.util.Scanner;
public class HmwLoop {
 public static void main(String[] args) {
double sum = 0;
for (double num1 = 1, num2 = 30; num1 <= 30 && num2 >= 1; num1++, num2--)

Calculate All Total Amounts By Adding All Rows

Jun 12, 2014

table.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
System.out.println("Value changed");
if(Float.parseFloat(table.getModel().getValueAt(table.getSelectedRow(), 4).toString()) != 0.0){
System.out.println(getTotal());
totalAmount.setText(""+getTotal());
}
}
});

This is what I've tried so far. What i want to do is to calculate all Total Amounts by adding all the rows (5th column only),as 5th column has total amount for 1 product, and set the text for a JTextField whenever the 5th column of any row changes its value.But this isn't working my way. I have also tried keyListener to trigger that change at Enter key typed but that also don't work for me.
